LOUISVILLE, Ky.—Democrat Hillary Clinton made a final push in Kentucky ahead of Tuesday’s presidential primary, looking to snap a losing streak against Sen. Bernie Sanders while battling a second front against Republican Donald Trump.

After all but conceding the past couple contests, Mrs. Clinton mounted a real campaign here. By Tuesday she is scheduled to have appeared at 11 events over three trips, including her visits to a pair of African-American churches Sunday morning. Her campaign also was on the air with TV ads.
